WARNING
All motorsports are hazardous.
Participants can suffer severe brain, head, or neck injuries causing permanent paralysis or
even death.
A properly fitted Leatt-Brace®, worn in conjunction with a full-face helmet, can help reduce the
incidence or severity of neck injuries, but no known safety device can eliminate the physical
risks inherent in any motorsport activity.
Read and follow all safety instructions
1
A Leatt-Brace® is not a substitute for skill or experience. Do not attempt potentially hazardous maneuvers while wearing
a Leatt-Brace® that you would not attempt without a brace.
The Leatt-Brace® must be correctly fitted to the wearer’s body. Follow the sizing and fitment directions in this manual
to insure that your brace fits properly.
Failure to achieve a correct fit of the Leatt-Brace® will reduce the effectiveness of the brace and may subject the
wearer to unexpected risks.
A cracked, bent, or deformed Leatt-Brace®, or any Leatt-Brace® worn by a user during an injury-producing accident or fall, should not be used again by anyone. Damage affecting the structural integrity and performance of the brace may not be visible to the naked eye.

User manual introduction
Welcome to the world of Leatt® and thank you for choosing our product. The Leatt-Brace® you have
purchased is based on years of academic research and extensive evaluation of the mechanisms of
head and neck injuries. Together with testing in test facilities and via simulation software, the brace
has been evaluated using various static and dynamic tests. The Leatt-Brace® is part of the protective
equipment ensemble available for use by participants in cycling and motor sports activities
The design rationale behind the Leatt-Brace® is to help bring the head to a controlled stop during
an accident/fall. This is achieved by providing a padded rigid structure that helps act as an
alternative load path for neck forces. Helmet impacts otherwise transmitted from the helmet to skull
and then to the neck are re-directed from the helmet to the brace and then to other body structures.
The design of the Leatt-Brace® helps prevent the helmet/head from projecting over the brace and
therefore helps prevent a fulcrum action which has been documented in literature pertaining to the
use of foam collar devices. The Leatt-Brace® may be worn with most types of motor sport body armor
and chest protectors.
The Leatt® STX RR neck brace system helps prevent the following extreme movements:
Hyperflexion
Hyperextension
Lateral
Hyperflexion
Posterior
Hypertranslation
Coupled Axial
Loading
Hyperflexion: Over-bending of the head in forward direction. Hyperextension: Over-bending
of the head in rearward direction. Lateral Hyperflexion: Over-bending of the head to one side.
Posterior Hypertranslation: Extreme movement of head and helmet, rearward on the neck.
Coupled Axial Loading: Axial forces acting in combination with other mechanisms.
Leatt® STX RR has been tested against the manufacturer’s specifications and EC Type-Examination
certification has been issued by RICOTEST Via Tione, 9 - 37010 Pastrengo (VR) Italy, Notified Body
No. 0498. It is CE marked to denote compliance with the EU Personal Protective Equipment Directive
89/686/EEC.
In addition to certification against the PPE directive, the Leatt-Brace® has also passed a battery of
additional tests compiled by the Notifying Body RICOTEST that includes elements from EN 16212:2003 (the European Standard for Motorcyclists Back Protectors), ISO 20344:2004 to evaluate
Impact resistance in the rear and a RICOTEST internal test protocol me-int-074-00 to evaluate
ergonomics, tensile strength and the content and comprehensiveness of the manufacturers
information.
All the materials that make up the Leatt-Brace® have passed chemical innocuousness testing as
required by the European Standard EN 340:2003 for general requirements of protective clothing.
Please e-mail any comments you might have to [email protected].
The Leatt® STX RR (Figure 1) has been designed to be set up in stages to suit your
requirements. Please follow the fitment process carefully. It should take you about 20 minutes to
complete.

and backwards movement of the wearer’s head and neck in a collision, or when impacting the
road surface. Leatt® Lab Quasi-Static Testing includes evaluations of the resistance of the LeattBrace® fastenings to opening in the event of an impact. The chemical content of the materials and
components used in the construction of the Leatt-Brace® has been assessed in accordance with
the requirements of EN 340:2003.

Leatt-Brace® sizing chart
The sizing chart below is a guide to determine if the STX RR will fit your body type. If you are out of
the range of the sizing chart or are unsure of your exact fit, please contact us, wearing the
STX RR with certain protectors could result in a safe fit. The sizing chart is based on your height
and chest circumference right below the arms, therefore make sure that you take the correct
measurements before utilizing the chart.

The folowing is to ensure that
your brace is setup correctly,
please go through entire
section. Fit the brace by pulling
it over your head with the
scapula wings attached (p7).
(Figure 2a) Please ensure that
the brace is facing the correct
way. (Figure 2b)
The size of the brace should be correct for your body shape and allows for adjustability to ensure
correct fitment and comfort. (Figure 3a) When correctly adjusted and worn with your helmet, the
Leatt-Brace® should allow for a full safe range of a rider’s head and neck movements (i.e. looking up,
looking down and looking side-to-side, such as when performing an over-the-shoulder check); the
Leatt-Brace® and the helmet must come into contact with each other as the full safe range of
normal riding head movement is reached. (Figure 3b)

Please ensure that the brace wings are correctly aligned over your shoulder as shown below:

If the wing does not align correctly please move on to step1 in the adjustment section (p7)
Check that you have the right helmet
rim clearance. Please use assistance
to do this measurement, do not do it
yourself. Place a ruler in the middle
of the upper rim of the brace at 90
to the ground, with your head in a
neutral (level) position. Remember
to do front and back. The helmet
rim should be within the safe zone,
the front and back safe zones are
between 50mm to 130 mm.(Figure 5)

If any resistance or discomfort is experienced when attempting to complete the full safe range of head
and neck movements, or if the brace does not make contact with the helmet when the full range of
movement is reached, further adjustment, or an alternative size of Leatt-Brace® may be required.
In extreme circumstances, it may be necessary to purchase an alternative model of helmet in order
to achieve the required level of compatibility and safety.
If the brace interferes with any of the above mentioned, please move on to the adjustment section
(p7) . Please ask the retailer or contact Leatt® if you require further advice on sizing, adjustment
or fitting.

Leatt-Brace® Adjustment
Your STX RR brace is supplied with the shoulder height adjuster fitted. The following steps will help
you adjust your Leatt-Brace® for the best fit. After adusting, return to Correct fitment p5 to ensure
your adjustments are accurate. Please refer to the Exploded view & parts list on p15.
Scapula wings
Figure 6a
To configure the scapula wings you must
open the strut clip. When the strut clip is
opened you can slide the upper scapula
wings in you favourable position. (Figure 7a)
Scapula wing
Close the strutclip when the scapula wing is
in the preferred position. (Figure 7b)
To rotate the scapula wings to fit your
racing gear, adjust the rotation screw with
the provided 4mm allen key (Figure 8a).
Rotate the scapula wings using the position
indicators to make sure they match up.
(Figure 8b)
By rotating the scapula wings you can use
the brace with a racing hump or without

Back height adjustment
In extreme cases, were a rider might not feel the brace if he bends his head backwards, or the
measurement on the back exceeds the indicated value on p6, it is recommended to attach the back
height adjuster for extra support. The adjuster is attached on top of the back assembly of the brace.

Proper care and Maintenance
Make it a habit to inspect your Leatt-Brace® as you would other safety equipment. Frequently worn
braces should be discarded and replaced every two years.
Do not make any alterations or modifications to your Leatt-Brace®. If you lose or damage
adjustment pins, hinges, struts, padding, or other components, purchase replacements from Leatt
Corporation.
Keep your Leatt-Brace® clean by washing it with plain soap and water. Solvents, abrasive
cleaners, and high heat can damage the brace and reduce its effectiveness just when you
need it the most.
